We have treated twenty-two cases with complete acromioclavicular dislocation by Dewar's procedure since 1985. Because the acromioclavicular joint has a little movement on shoulder abduction (so-called rankshaft-like motion) we think maintenance of its normal movement is better to treat the acromioclavicular dislocation.
Nine cases of twenty-two cases were reported. Almost all cases showed satisfactory results.
